A week or so ago, I had an itchy red circle around one of my (Novolog) injection sites from that day. There was a (tiny) little hard knot underneath, too. I had run out of alcohol prep pads, which I usually use to wipe my needles in between uses (I use the same needle for an entire day), so I assumed there was probably just some irritation from something on the needle, and it was gone by the next morning.
Well, it happened again yesterday, with a needle I’d been cleaning, and then last night, I injected my Levemir with a brand new needle, and I actually got raised hives around the site. It was incredibly itchy.
I have no idea what’s going on. I do have pretty bad environmental allergies, and I suspect I’m having either skin reactions to something off and on, or I’ve developed an inappropriate hive-like response to stress, as I will sometimes randomly break out in itchy bumps when I’m stressed/my body is physically stressed. This has also happened several times in the past couple of months (which have been unusually stressful), so I’m not sure if it’s connected. The only other thought I had was that I started using ReliOn brand pen needles a couple weeks ago. I’m just confused because I would assume that, if this is related to an allergic reaction to something, it would be more consistent (every time I inject)?
